At first glance I wasn't sure about this new 3Acts from Dan Meyer but then I got to the end of this video and totally loved it. So good for anyone teaching ratios. And I love the text messages a la Sherlock (as a nice added touch). Now to get the full 3Acts files you will have go to Dan's 101qs.com site and become a member but its worth it.

Do you need data to show that it is a better deal to buy a bigger pizza instead of a smaller one? How about 74,476 data points. I really have to learn how to program in Python. So many cool things that you can do. Anyway, if you want a cool use of data or a connection to area of a circle, here you go. Complete with interactive graph. And then if that data isn't enough they have collected pizza price data by US city. See that here.

From Yummy Math comes a post about movie ticket prices over the years. Movie data is one of my favs. Especially when you couple ticket price data (from Box Office Mojo) with box office record data like the top grossing films of all time (from Movieweb) . Because the thing about records like that is that they will likely always be broken for two reasons: 1) ticket prices will always go up (so less tickets need to be sold to accumulate the same total) and 2) there are more people available every year to go to movies.

I know the show Numb3rs has not been on the air for years but that doesn't mean you still can't use it to make connections between math curriculum and the show. And so here are a couple of sites that take every episode and connect it to the actual math used.

One of the expectations in grade 9 math is to develop the formula for the volume of a pyramid. If you have the proper manipulatives then its easy. If you don't then this video will do the trick (too bad the music is a bit cheesy). Thanks to Erina Shkodra for this one.

The connection to math may not be obvious right away for this one but I think all of the double negatives means you could use this to simulate multiplying by negative one repeatedly and thus either have a positive or negative answer. Thanks to Dale Wilson for this one

This clip from the movie Pay it Forward could be a great introduction to exponential growth. Whether it be in Grade 8 or even as a minds on for dealing with exponential functions in grade 11 or grade 12. Thanks to Andrena Misener for this one
